To be really sure, I start capture before plugging device to hub.
There are enumeration, and descriptors are properly parsed. I can
place pcap somewhere, if this may help.

yes it could be useful. On my side I'm using USBPcap and USB Class ID, Subclass ID and Protocol are properly populated when the capture contains the USB enumeration.
You did not indicate us which Wireshark version you are using.
